Oh really, why is that then? I fitted that same motor into a sportsboat, and it ran fine for 9+years. And what about Chevy V8's, the same motor as used by Mercruiser and Volvo for 20+ years.

Hope I get caught behind you at 2000 revs on a duel carraigeway. Round town you'd be like driving Miss daisy.
My (latest) motor's only turning around 2000 RPM at 60 MPH...and it'll sit there all day, quite happily......

Is your mower oil injected?

Try dipping half of the mower in the sea and running it on moist salty air. I wonder how long it would last then. It takes a bit of engineering to extract 150/200 hp out of a 2st and keep it reliable. Your mower is a plug and a coil.

Yep, the only difference is that the Mercruiser 5.7 ltr has a mechanical fuel pump run off of the crank and the 350 Chevy has an electronic pump (less sparks). Yamaha use it also. It's a cast-iron monster, as long as it's flushed and well winterised, it'll go on for ever.

I dont understand. How can a 2-stroke mower (or any engine for that matter) run without any oil?
